[Bug 475418] Re: mythfrontend.real crashed with SIGSEGV

[HX_unbanned]

Hello!
To reproduction might be pretty easy, but I think it is pretty tricky bug -
that is - it migh require only one or to previous triggers or data caches /
storages / saves / any memory operation, so it needs some time to reproduce
same behavior - crash.
Although - this is very important and very frustrating bug because it simply
may cause memory leftovers or leaks in some registers or buffers.

I will try my best.

- No, now entering on Watch TV does not crash to desktop, even if there is
audio playback in background.

May I ask any logging options to be able to provide info for you?

And - there is still some weird info in System Info menu - in the first tab,
where the mythtvdatabase daemon data has been gathered and viewed, no info
about Last Opened, Played, Viewed available and three yellow warnings
messages inside the groupbox..
